Some of these remove photos after asking, some of them have just removed any comments and banned me after contacting (and after that I can see the pics when logged out.... lol) and some of them obviously don't even visit there, since they haven't removed any of my comments.

Every time I do a search with my photos, I find new groups from vkontakte using tons of stolen images. Seems like this a thing that keeps happening there and we basically cannot do anything to stop it.
